In ros version 1.1.9 rosmake fails to drop ROS_NOBUILD files into directories corrrectly making shared installs and the debians not work correctly. The symptom is that rosmake reports "rospack failed to build" ROS 1.1.10 is released with the fix and the debians are being rebuilt. If you already updated the cturtle debs below is a script which will place the files for you. In a few hours the new debs will be posted. Sorry for the inconvenience, Tully To fix it: su . /opt/ros/cturtle/setup.sh python add_nobuild.py This script will touch ROS_NOBUILD in all packages in you environment. -- Tully Foote Systems Engineer Willow Garage, Inc. tfoote@willowgarage.com (650) 475-2827
